ANP Citizen Science Report
Schoodic Institute at Acadia National Park
Introduction
Welcome to the weekly report of iNaturalist and eBird records. These are all observations submitted during the last week for species that Acadia National Park managers have identified as being of management interest.
These data for this report comes from two of the largest open source citizen science projects: iNaturalist and eBird. The records here are both casual and research grade observations, so erroneous identifications are possible.Pest & Invasive Species
